Chemistry is one of the few subjects that students find really interesting for themselves. It prepares you for a career in various domains like Pharmaceutical research, environmental causes, etc. The National Eligibility Entrance Test (NEET), formerly known as the All India Pre-Medical Test (AIPMT), is the qualifying test for MBBS and BDS programs in Indian medical and dental colleges.
The syllabus is the same as previous years only the paper pattern has changed this time. Students are now provided with 3 hours and 20 minutes to complete the exam. There will be 2 sections in each subject. Section A will contain 35 questions and section B will contain 15 questions. Out of these 15 questions in section B, students must attempt any 10 questions.
You can download the syllabus from the link below.
On this page, we have provided direct and free access to the NEET-UG Chemistry Syllabus 2025.

You must work on increasing your understanding of Organic Chemistry if you want to perform well on the NEET. Conversion questions make up a significant portion of this subject, so pay close attention to them. If you want to feel more competent and confident when handling Organic Chemistry problems, practise these questions a lot.
Reaction mechanisms, functional groupings, and named reactions must all be thoroughly understood. Your chances of receiving a high grade on the NEET Chemistry exam will be significantly increased by systematically practising Organic Chemistry.
Graphs play a significant part in NEET Chemistry. Making a mental note of the graphs included in the NCERT textbooks is a smart way to succeed. Understanding the patterns, answers, and physical characteristics displayed in these graphs will enable you to easily consult them during the test.
To help you recall the key points in these graphs, it might be useful to highlight them and go over them often. This not only improves in question responding but also enhances your general comprehension of Chemistry concepts.
Using flashcards is another useful technique for quickly recalling key ideas, formulas, and emotions. Make flashcards with the main ideas and mnemonics highlighted for every subject. In your spare time or during brief breaks, go over these flashcards.
Revision with flashcards is tedious, which helps to improve memory and speed up material recall. You can study important topics in the final moments before the NEET test by using this method.
You must include mock exams in your NEET study schedule. By using a timer and adhering to the official structure, these examinations replicate the experience of an actual exam. They assess your knowledge but also assist you in refining your exam approach and time management.
Using practice exams, determine your weak points so that you may concentrate on them during revision. Regular mock test practice increases confidence and experience with the format of the exam.
Maintaining a well-thought-out strategy is necessary to achieve a score of 180 in the NEET 2025 Chemistry portion. You must thoroughly study the appropriate literature and do a thorough revision. Given the variety of subjects covered in Organic and Inorganic Chemistry, this is extremely crucial. Practice regularly thoroughly comprehend the NCERT content, and concentrate on your weak areas. You can prepare for the test with the aid of these measures.
Yes, the NEET 2025 Chemistry syllabus comprises the Class 11 and Class 12 NCERT syllabus.
Almost 35% of the syllabus was deleted. The deleted chapters from the NEET Chemistry Syllabus 2025 include UNIT V: States of Matter: Gases and Liquids, UNIT IX: Hydrogen, UNIT X: S-Block Elements (Alkali and Alkaline Earth Metals), and UNIT XIV: Environmental Chemistry.
The NEET Chemistry 2025 section in the exam is for 180 marks, with aldehydes, ketones, and carboxylic acids, followed by chemical bonding, molecular structure, and hydrocarbons.
